Spool FX-170 N20 N26 Upgraded High Pressure Pump Kit

The Spool FX-170 is a high-performance high-pressure fuel pump designed specifically for the BMW N20/N26 engines. Featuring a larger bore size compared to the stock pump, the FX-170 delivers approximately 50% more flow, enhancing fuel delivery for high-performance applications. It is fully E85 compatible and offers a straightforward plug-and-play installation with no need for cutting or splicing. Additionally, the FX-170 operates at 25% higher pressure than stock pumps, allowing injectors to flow more fuel within the same opening time, making it ideal for running higher ethanol concentrations and supporting larger turbos.

Why Do You Need It?

The stock high-pressure fuel pump (HPFP) in the N20 engines can limit performance when increasing power or tuning the motor. The FX-170 addresses this limitation by providing a 50% increase in flow and improved injector performance. This upgrade raises the fueling limits, enabling the use of bigger turbos and higher ethanol blends, thereby optimizing the engine’s performance and capability.

What Does the Kit Include?

• 1 x FX-170 upgraded high-pressure fuel pump
• Upgraded fuel lines and all necessary installation hardware

Optional:

• Ethanol Content Monitor kit with mobile app
• Bosch spec 10-micron high-flow fuel filter

Spool 10-Micron Filter Unit

The included 10-micron filter unit offers superior filtration without causing any noticeable pressure drop in the low-pressure fuel system. This filter is highly recommended to protect the high-pressure pump and injectors from debris and contaminants.

Are Tune Changes Required?

Yes, calibration changes are required when installing the FX-170 pump. It is crucial to apply these changes before starting the vehicle to prevent potential damage and avoid voiding the warranty. Spool Performance can provide calibration details to your current tuner or assist you in connecting with experienced tuners. While Spool Performance does not offer custom tunes, we can support you with any questions your tuner may have.

Low Pressure Fuel Pump Upgrade:

Proper low-pressure fueling is essential for the durability and performance of high-pressure pumps and injectors in a direct injection system. Inadequate low-pressure fueling can cause damage due to improper lubrication from controlled fuel leakage, leading to potential warranty issues. Ensure your fuel system build includes necessary low-pressure upgrades to prevent such damage.
